G461/G462
In order to enable the solid machining of inside corners in certain situations with the activation and deactivation of
tool radius compensation, commands G461 und G462 have been introduced and the approach/retraction
strategy has thus been extended for tool radius compensation.
• G461
If no intersection is possible between the last TRC block and a previous block, the control calculates an
intersection by extending the offset curve of this block with a circle whose center point coincides with the end
point of the noncorrected block, and whose radius is equal to the tool radius.
• G462
If no intersection is possible between the last TRC block and a previous block, the control calculates an
intersection by inserting a straight line at the end point of the last block with tool radius compensation (the
block is extended by its end tangent).
Changing from G40 to G41/42
The change from G40 to G41/G42 and vice versa is no longer treated as a tool change for tools with relevant tool
point direction (turning and grinding tools).
Tool compensation environments
Functions, which enable the following actions in relation to the current states of tool data, are available in SW 7.1:
•Save
•Deletion
•Read
•Modify
Some of the functions were previously implemented in measuring cycles. They are now universally available.
A further function can be used to determine information about the assignment of the tool lengths of the active tool
to the abscissa, ordinate and applicate.
